Open comments again

OK so after some 5 minutes of reading the help I have done a minor configuration change to the commenting system, which requires you to type in a word as shown on a picture. This is to validate someone is actually sitting in front of the computer typing the comment. I'm not sure it will do the trick to 100%, but at least it will prevent the automated spam.
I give it a try for some time, and if we still get polluted I'll reverse back to members-only.

On a side note, the whole base-team (ze board + contributor) is registered and activated now, so I hope the flow of entries will increase.
